Hail is a kind of solid impetus that is composed of balls or irregular lumps of ice, each of which is reported as a hailstone. A discrepancy of soft hail (which is made by frost and hail, which are smaller and clearer). In this sense, we can detail which causes hail for this is simply possible in most storms, since it originates within the cumulonimbus, that is, annex of the 2 nautical miles (3,7 km) of the parent storm.
What causes hail or how is it formed?
Many people tend to wonder what causes hail? Well, first we would have to point out that hail originates with the representation of a solid particle. This is pulled by strong winds rising within the cloud, to which particles of water. Climbing causes these atoms to freeze, curdling.
Likewise, upon reaching the upper region of the cloud, the hail descends towards the land by its own weight. In its collapse, many of the ice covers that were formed during its degree, can thaw, returning to its particular liquid state.
However, they do not disengage and still remain within the cumulonimbus, it can be caught again by another steep air current and be transported to the upper areas of the cloud. cloud. This causes the adherence of a new layer of water particles and their freezing. This period can happen several times, until the hail takes on a space and weight, that the steep currents of air inside the cloud, do not have enough force to move it, thus precipitating to the ground.
In this way, the hailstones gain dimension and create their layers (like an onion) of white and crystalline ice. Now, what causes hail is simply that the white ice responds to the large sum representation of a government-protected within the water, this marks the extent of the hail within the cloud. The water curdles without giving the air time to come out, so the ice made is completely white.
Conversely, crystalline ice shows the decline of granizo. Its ice cap is thinned and the air is removed. That is why the outer mantle of the hail is mostly clear, however sometimes that ice mantle, during its collapse to the ground, melts, leaving the white ice mantle in the first place.
This hypothesis about its creation has been rejected when it was stated that not precisely each of these layers symbolized the degree and descent within the cloud, but rather the passage of the stone through uneven areas of the cloud. cloud, where the water gatherings vary.
When the hail crosses an area with a large crowd of supercooled water droplets, the transparent ice layer is created, while when it crosses an area of water gas, white ice is formed. Now, according to these data of interest referring to what causes hail, we can establish that thanks to the sharp winds that sometimes reach 180 km/h, the hail stone can be preserved for a long time inside the cloud and reach great extensions, until achieving a volume that does not allow it to be preserved in it and by its own work of gravity it is thrown into the land.
Generally the hail is rounded, however, on some occasions it can exhibit an irregular shape. This depends on the representation when the hail has been wiggling inside the cloud.
Factors that help with hail formations
Hail is more common in the interior continental regions of the mid-latitudes. Since hail creation is much more possible when the cooling level is below the 3 m (400 ft) elevation, the dry air current causes the representation of strong thunderstorms over the continents, and this increases the periodicity of granizo, through the impulse of freezing by gasification.
In this sense, this subdues the level of cooling of storm clouds, giving the hail a greater body. As a result, hail is actually less common in the tropics, despite a much higher periodicity of storms, than in the mid-latitudes, because the atmosphere in the tropics it tends to be hotter in a much larger depression.
Equally, it is significant to show that what causes hail is that in the tropics it happens especially at higher elevations. But the development of hail becomes profoundly small, when the temperature ambient proceed below −30 °C (−22 °F). Supercooled water droplets become anomalous at these temperatures.
Near thunderstorms, hail is more possible, within the cloud at altitudes above 6 m (100 ft). Between 20 m (000 ft) and 3 m (000 ft).
All told, 60 percent of the hail is still inside the storm, and 40 percent is now airborne at the base of 'anvil'. Below 3 m (000 ft), hail is equally commodified in the environments of a 10 km (000 nautical mile) storm path.
Final conclusions regarding what causes hail
Hail forms in cumulonimbus clouds, in other words, in clouds. These clouds are of great vertical progress, internally created by a column of warm and humid air that rises in the form of a rotating spiral. They are responsible for electrical storms and Rain sharp.
Inside these clouds, very cold water droplets change into ice as they climb to higher areas of the cloud due to fluids forcing them up and down. For the creation of the hail, a minimum temperature of -15ºC is requested and it is that the hail is created in the highest part of these clouds where the temperature is very low. There the crystals of ice they progress with the drops of water that are thrown by the steep currents.
In this sense, when it reaches a sufficiently large dimension, it cannot last longer in the air and falls by the action of gravity, pulling on its way inside the cloud. droplets.
The hail progresses thus overcoming new layers of ice and it is that several periods of ascent and descent can take place until the hailstone is so loaded that the standard ones are not suitable to exalt again. As they fall, layers of the particular hail and the ball that reaches us is always smaller.
In other words, if they can cut a ball of hail in half, what they will be able to show is a representation somewhat similar to an onion and it is that these ascending and descending movements are noticeable inside. The white ice responds to the representation of a large sum of air within the water, this marks the degree of hail within the cloud.
Finally, what causes hail is that the water curdles without giving the air time to come out, so the ice done is completely white. In contrast, clear ice shows the descent of hail. Its ice blanket liquefies and the air is removed.
